MNA can be used to influence packet-forwarding decisions, carry additional Operations, Administration, and Maintenance (OAM) information in the MPLS packet, or perform user-defined operations.\n\nThis document updates RFC 9789 to refine the list of pieces of information that must be included in any document that defines an MNA.",
